Gasoline prices averaged $3.448 a gallon in the Seattle-Tacoma-Bellevue area in May 2021, the U.S. Bureau of Labor Statistics reported today.

The average cost of utility (piped) gas at $1.186 per therm in May was more than the $1.090 per therm spent last year.

At $3.448 a gallon, Seattle area consumers paid 13.4 percent more than the $3.041 national average in May 2011.

A year earlier, area consumers paid 5.1 percent more per therm for natural gas compared to the nation.

Technical Note

Average prices are estimated from Consumer Price Index (CPI) data for selected commodity series to support the research and analytic needs of CPI data users. Average prices for electricity, utility (piped) gas, and gasoline are published monthly for the U.S. city average, the 4 regions, 9 divisions, 2 population size classes, 8 region/size-class cross-classifications, and the 23 largest local index areas. For electricity, average prices per kilowatt-hour (kWh) are published. For utility (piped) gas, average prices per therm, are published. For gasoline, the average price per gallon is published. Average prices for commonly available grades of gasoline are published as well as the average price across all grades.

All eligible prices are converted to a price per normalized quantity. These prices are then used to estimate a price for a defined fixed quantity. The average price per kilowatt-hour represents the total bill divided by the kilowatt-hour usage. The total bill is the sum of all items applicable to all consumers appearing on an electricity bill including, but not limited to, variable rates per kWh, fixed costs, taxes, surcharges, and credits. This calculation also applies to the average price per therm for utility (piped) gas.
